superbolt question

[ramsee1]

Howdy all. I've been seeing posts and comments about how the superbolt sleeve doesn't really last too long. With all due respect to everyone who researched and made this product, but why can't the entire bolt be made of delrin? It seems inevitable that if you have a plastic-like cuff wrapped around a metal base that eventually the thing is going to shred. I only ask because I see many other marker brands producing a one piece delrin bolt work with a good amount of success. Has anyone tried to machine a bolt without a metal base?

The bolt is derlin exept for the parts which really get beat on, such as where the sear catches the bolt. If that was derlin, it would only last a few hundred shots.

It is all delrin? I am under the impression the whole thing is metal and just the sleeve is delrin:

I'm curious what makes the conditions so harsh that it's different from any other bolt that goes back and forth in a chamber. With one piece I would think the bolt would just tend to wear a little while adjusting to the size of the chamber and not get torn apart (referring to picture posted in the main forum). I'd like to see a working diagram of a mag being fired.

You don't need to see a working diagram if you know enough about your gun. Its fairly easy to figure out. Next time you have your gun apart, look at the bolt and the sear. You will be able to see how the sear grabs the bolt. The amount of force being exerted on that point is too great for derlin to handle. Also, the bolt shoots back in about 1/50th of a seconts, so if the plunger didn't go in perfectly straight for some reason and was made of derlin it would snap. Theirfore the only part left to make of derlin is the sleeve.
Also, I think the plunger is drilled out to make it lighter?

Well I know enough to know the bolt is all metal
Yes I see how everything works now (I am new to mags). I have a prototype bolt in the works which I think is a nice solution. Thank you for your input Pyro, it is much appreciated.
